AVS13 – AVS100 / A/C Guard — single-phase automatic voltage relays 13–100 A
Country: United Kingdom · Model: AVS13 – AVS100 / A/C Guard
AVS single-phase voltage relays switch the load off when the mains goes outside permitted limits and restore power after a delay. The range includes plug-in socket adapters for 13–16 A, panel-mounted AVS30 and the 100 A AVS100 for a whole site, as well as the A/C Guard for 16/20/25 A for air conditioners.

Description
The relays monitor overvoltage and undervoltage and suppress the surges and spikes that occur when the mains is restored after an outage. The AVS15 and AVS30 add protection against neutral loss, which is dangerous for single-phase consumers in a three-phase building network, because line voltage can reach them. The restart delay is adjustable from 10 s to 10 min depending on the model. A long delay is needed for refrigerator and air-conditioner compressors so that the pressure in the circuit has time to equalize. The AVS15/16 withstand an inrush current of up to 70 A. Socket models are plugged in between the socket and the plug, while the AVS30 and A/C Guard have a wall-mounting enclosure with cable entries.
How to choose
The relay rating must be not less than the working current of the protected line, and for compressor equipment the inrush current is also taken into account. A separate 13–16 A unit is installed for a single consumer, while the AVS100 at the entry protects a whole house or office. For household appliances with a plug it is simpler to take the plug-in iS / iSense Guards at 6–10 A, and three-phase motors and pumps need the AVS303 or AVS3P-0.

FAQ
What switch-on delay does the AVS voltage relay have?
The delay is adjustable from 10 s to 10 min, and the exact range depends on the model. For refrigerators and air conditioners a longer delay is set so that the compressor does not start under pressure.
Which AVS models protect against neutral loss?
Protection against neutral loss is available in the AVS15 and AVS30. The other models of the line react to overvoltage and undervoltage, surges and spikes when the mains is restored.
What inrush current can the AVS15 or AVS16 withstand?
The AVS15/16 are rated for an inrush current of up to 70 A, so they suit refrigerators and small compressor units.
How does the A/C Guard differ from the plug-in AVS?
The A/C Guard is made for 16/20/25 A for fixed connection of air conditioners, whereas the plug-in AVS13–AVS16 are connected between the plug and the socket.
